Fly Ash As Replacement Of Sand

Vol. 2, Issue 5, May 2013 USE of FLYASH as PARTIAL

On experimental analysis, it has also been observed that the mortar of the ratio 1:1:5 (cement : flyash : sand) when the replacement of cement is made by flyash, it gives lesser strength in comparison to the replacement of sand by flyash as shown in Tables 4 and 5. Furthermore, the consumption of flyash is also reduced appreciably. With the aim

Fly ash Wikipedia

Fly ash can replace either the Portland cement or fine aggregate (in most cases, river sand) as a filler material. High fly ash content mixes contain nearly all fly ash, with a small percentage of Portland cement and enough water to make the mix flowable. Low fly ash content mixes contain a high percentage of filler material, and a low
